Medical coding services that hold up under payer review

Coding is where documentation, compliance and revenue meet. Our coders work specialty by specialty — ICD-10-CM, CPT, HCPCS and modifiers — so claims are supported by the note, not by habit or by a template.

Undercoding quietly costs a practice a percentage of every visit. Overcoding costs far more, later, with interest. Both come from the same place: coding decided by routine instead of by what the documentation actually supports.

Our coding service pairs certified coders with specialty rules and payer edits, and closes the loop with the clinician. When a note will not support the level billed, you hear about the note — not just a lowered code.

What our coding services cover

Coding runs either as a standalone service or inside a full billing engagement. Either way the deliverable is the same: correct codes, defensible documentation and feedback your providers can act on.

  • ICD-10-CM diagnosis coding to the highest supported specificity
  • CPT and HCPCS procedure coding with modifier review
  • E/M level assignment against 2021+ documentation guidelines
  • Surgical and global-period coding, including bundling checks
  • NCCI edit, LCD and payer-policy screening before submission
  • Retrospective and prospective coding audits with error rates
  • Provider-facing documentation feedback, written plainly

Specialty coding, not general coding

Behavioral health time units, orthopedic global periods, cardiology device checks, pain management image guidance, radiology professional-versus-global splits — these are separate disciplines. Coders assigned to your account work your specialty, and the specialty pages on this site show the code families and denial patterns we handle for each.

Compliance posture

Coding accuracy is a compliance question as much as a revenue one. We operate HIPAA-aligned workflows, sign a Business Associate Agreement before any protected health information moves, and limit account access to assigned staff. Where documentation does not support a code, we do not bill it.

How coding accuracy shows up in collections

Clean coding reduces the denial categories that cost the most time: medical necessity, bundling, modifier mismatch and missing specificity. Fewer of those means fewer appeals, shorter A/R and a first-pass acceptance rate that stays near 99% instead of drifting down each quarter.

Frequently asked questions

Are your medical coders certified?
Yes. Coding is performed by certified coders assigned by specialty, with a second-level review process for high-risk code families such as surgical globals and E/M levels.
Can we buy coding without billing?
Yes. Coding, coding audits and billing are separate services. Many practices start with a coding audit, then decide what to outsource.
How do you handle documentation that does not support a code?
We code what the note supports and send written feedback to the provider explaining what would have supported the higher level. We do not upcode to protect a number.
How often should a practice run a coding audit?
Annually at minimum, and after any change in providers, specialty mix or payer contracts. Practices with recent medical-necessity denials should audit sooner.
Do you code for telehealth?
Yes, including place-of-service and modifier rules, which still vary by payer and by state Medicaid programme.
